NAL. a'corporation of New York Al pli cation- March 1 5,1 1932. serial No. 5983527 A a 'ig fll Claims. My invention relates toswrapping machines, and has special reference to gum wrappingimachines in which 'individualsticks or pieces of gum arefirst Wrapped in paper-linedfoil; a paper lar53 bel is placed around the foil wrapper with its edges overlapping and glued together; then the individual pieces are stackedin'groups, usually of five, and the groups or'stacks arethen enclosed by a paperlabel to complete therpackage.

In gum wrapping machinesof this type, it has heretofore been a serious problem to stack thein-' dividual pieces after the labels have been applied without more or less opening up orotherwise deranging the newly pasted overlapping seam of v; the labels. Such derangement of -the seamis likely to-result in crumpling and: loosening the label and paper-lined foilwrapper and jamming the gum during the stacking-and subsequent operationsso'that the completed package is liable to have one -ormor ofthe-wrapped; pieces of gum in a distorted or defective condition, thus effecting "the appearancex'offithe package as a whole, and preventing the proper application of the label thatenclos'es theseve'ral stacked pieces,-.9

The principal object of the present invention -is to provide novel and-improved means for stack-- ing the individual "sticks or pieces of gum after" the labels have beenapplied which overcomes the disadvantages above' described' of the 'prior constructions. Another object of the invention 'is to provide a novel and improved wrapping machine of the character indicated.

The several features of the inventiom'whereby these" and other objects may be" attained, will be readily understoo'dfrom thefoll'o'wing descrip== tion and accompanying drawings' in which:

A s

, The pieces of .gumare fed in spaced relation beneath a. guide-barn to adefinite position or station in front; of1sa'id guide bar, any suitable devices beingrprovided for thus feeding the gum, such as the 'members .14, these 1 members also servingto eject-the pieces from the wrapping head and upon :the. table. as above described. The table 10 is made .up of: longitudinally extending rails 16,:1there. being three such rails which are spaced apart as shown. 1 "The..pa .rts 0f..:the machine above referred to may be-aridiipreferably' are of a well known con-. struction. as; I 1 i r z.

In accordance with the present invention, novel "and improved means are provided for stacking the individualpi'eces of gum in groups. of five pieces as they aredelivered to the station in front of thezguidebar .12,.a.s above described. As shown; the table 10 isprovided with an upwardly opening transverserecessor slot 18 which extends across 'theLthree rails or the table and is ofsslightly. greater widthithan the :width of the pieces of -gum..: The. top of the table has an upward" projection "forming an abutment -19 whiclr forms 'an extension of the *rear wall of thesl'ot-18. A=hori'zontal support 20 is mounted to slidevertically lll SflidrSlOt 18." Thissupport comprisesaxbar-zwhich is secured upon the upper end of a rod 22thatis mounted" to slide in a vertical-aperture which extends through the bottom wallof the slotted portion of the central rail of the table 10. The lower end of thisxrodis secured to a yoke 24 whichiembraces and is mounted to slide on a block 26 that is loosely mounted ona' rotating shaft 28. The yoke 24 carries a cam roll 30 which is held in engagement with. a cam 32 secured on the end of the shaft 28, by means of a coiled spring 34 interposed between the upper side of the block 26 and the lower end of the rod 22. The shaft 28 is suitably journaled in bearings 36 on the machine frame and is driven through a gear 38 secured thereon, which is operatively engaged by a pinion 40 secured on a drive shaft 42.

Above the slot 18 and plunger 20 there are guide rolls 44 which are carried on the ends of arms 46 secured to a shaft 48 mounted for pivotal movementin bearings in the guide bar 12. The rolls 44 aregpres'sed downwardly a limited distance by means of a spring 50 coiled about the shaft 48 and having one end secured .to the shaft and its other end held fixed to the guide bar 12, the downward movement of the arms being limited by the engagement of a stop pin 51 on one of themwiththe machine] frame.

At the start of the operation of the machine,

the support 20 is positioned substantially level with the top surface of the table 10.; Asthefirst piece of gum delivered from the wrapping head 2 withthe label. applied'is fed over the been thus stacked, the cam=roll 30 rides off of the point 52st the cam 32;wherei1pon the spring 34 immediately acts toelevate the support to position its top surface and the underside of the lowermost piece of 'gumslightlyabove the top of theiabutmentlQKFig. 1). Suitable devices (not shown) then'f'act to carrygthe stackof gum off of the support and fromibeneath the rolls 4-4, and deliver them to the usual mechanism for wrap,- ping. the label. about the stackto complete'the package, 1. :.L. 3

- the stack has been thus discharged from the "support: 20, the v 'support is'lowerem ready to. receive the next piece of gum fed over thettable 10, asab'ove describedii a i ".It willbe; apparent that my improved gum stacking mechanism simpleini. construction and positive and accurate in operation. -,As the pieceswof gum are severally iedbver and upon the: support 20,-"as the. outer lap of the newly pasted label is nnderneathtand zisfiirected ,rearw'ardlywith relation to theidirection of feed of the gum, there is nozdang'er of the seam catching and opening up or becoming deranged but to the contrary as thepieces are 'fcd one over the other they tend by frictional engagement between them to tighten thelabelon the enclosing paper-lined roil wrapper fand to :smoothlykpress the-'overlappmg edges'nf the label together.

. As will be evident to those skilled in the .art my inventionpermits various modifications without departing fromi'the; spirit thereof; or the scope "ofthe appendedclaims.
